+JMeter <b>properties</b> are defined in jmeter.properties (see <a 
href="get-started.html#configuring_jmeter">Gettting Started - Configuring 
JMeter</a> for more details).
+<br></br>
+Properties are global to jmeter, and are used to define some of the defaults 
JMeter uses.
+For example the property remote_hosts defines the servers that JMeter will try 
to run remotely.
+Properties can be referenced in test plans 
+- see <a href="functions.html#__property">Functions - read a property</a> -
+but cannot be used for thread-specific values.
+</p>
+<p>
+JMeter <b>variables</b> are local to each thread. The values may be the same 
for each thread, or they may be different.
+<br></br>
+If a variable is updated by a thread, only the thread copy of the variable is 
changed.
+For example the <complink name="Regular Expression Extractor"/> Post-Processor 
+will set its variables according to the sample that its thread has read, and 
these can be used later
+by the same thread.
+For details of how to reference variables and functions, see <a 
href="functions.html">Functions and Variables</a>
